SANYO assumes no responsibility for equipment failures that result from using products at values that. If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC. In this case, hum noise may be generated.

So, be careful of the transformer regulation.

The following is a formula to be used to calculate Datasheer. For AC power supply, however, it is recommended to actually measure Pd on the transformer of each.

Supply voltage at quiescent mode. Supply voltage at Pd max. Supply voltage at maximum output. Example of Heat Sink Mounting Method.

The heat sink must be of such a shape as to be able to dissipate heat from the IC plastic area and fin area and is soldered to. For the size of the heat sink, refer to the Pd — Ta characteristic. The material of the. It is recommended to apply silicone grease to the IC.

SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values such as maximum ratings, operating condition ranges,or other parameters listed in products specifications of any and all SANYO products described or contained herein.

If the transformer regulation is not as specified, the supply voltage drops momentarily when the motor of an AC- la450 set is turned ON. DC muting To dahasheet DC muting by controlling the NF pin, it is recommended to use the circuit configuration shown right. The potential at point A is set to 3.

Thermal Design Since the DIPF package is such that the Cu-foiled area of the printed circuit board is used to dissipate heat, make the Cu-foiled area in the vicinity datasheef the heat sink of the IC as large as possible when designing the printed circuit board.

The use of the Cu-foiled area indicated by shading in the above-mentioned sample printed circuit pattern makes it possible to dissipate more heat.

So, it is recom- mended to use the printed circuit board together with the heat sink. The following is a formula to be used to calculate Pd for stereo use. For AC power supply, however, it is recommended to actually measure Pd on the transformer of each set. Supply voltage at quiescent mode V CC Pd: Supply voltage at Pd max V CC 1: Supply voltage at maximum output r: The material of the heat sink is recommended to be copper or iron which is solderable.

It is recommended to datasheey silicone grease to the IC plastic area to reduce thermal resistance between the heat sink and the IC plastic area.
